The Best CLA Supplements

Research shows a clear link between CLA supplement usage and a reduction in body fat mass. We explore in more depth and find out which brands are best to buy.

Weight Loss From CLA Supplements

Conjugated Linoleic Acid (CLA) is a naturally occurring fatty acid that has long been considered a great weight loss aid. Though it’s found naturally in meats and dairy products, many choose to boost their intake with CLA supplements.

While studies on it’s effectiveness have resulted in contradictory verdicts in the past, the most in-depth study undertaken on the effects of CLA concluded that it does result in lower body fat mass in healthy adults. Great news!

If you’re in a hurry and we had to pick one out of the many available CLA supplements, we’d suggest you try out these CLA Softgels by BulkSupplements. Read on to find out more about CLA and the various options available.

What’s The Best CLA Supplement?

Most of the CLA supplements you’ll find available online have a very similar list of ingredients. To get the most out of supplementing CLA in your diet, you should opt for a product that has a minimum of 80% concentration.

Aside from the concentration of CLA – be sure to keep an eye out for other ingredients that make certain brands unsuitable for those who are vegetarian or have allergies. For example, bovine gelatin is a common ingredient in supplement capsules. Below are what we believe to be the best CLA supplement brands for those looking to lose body fat.

BulkSupplements CLA Softgels

If you are looking for a way to boost your metabolic rate and muscle mass, these CLA supplements may be the way to go. The soft gel capsules contain ingredients that are lab tested to guarantee their purity and effectiveness. As with most CLA supplements, the conjugated linoleic acid is derived from safflower oil, with the oil coming from the seed rather than the flower itself.

You won’t find any soy, yeast, dairy, sugar, gluten or additives in this product. You will however find glycerin and bovine gelatin, something vegans and vegetarians may want to avoid.

One serving is considered 2 capsules, and this product can be bought in 100, 300, and 6,000 counts. You save money when buying in larger quantities, but keep in mind that this product has a recommended shelf-life of 2 years. Be sure to store them in their bag and out of direct sunlight.

Of the 1000 mg Tonalin CLA, 78 to 84% is active Conjugated Linoleic Acid. Although a range instead of a number isn’t ideal, the bottom number is nearly as high as other products. Another great thing about this supplement is that it comes in rapid-release soft gels. A serving is one soft gel.

What To Know About CLA Supplements

Buying CLA Supplement Guide

CLA, or Conjugated Linoleic Acid, is known to have several amazing health benefits. CLA is not something that your body naturally produces, but you can get it from consuming dairy products. Most people interested in building muscles and losing weight do not want to overdo it on dairy based foods, so opt for supplements instead.

This guide is designed to go over what CLA is, why people use it, what the potential side effects are, how to find the right supplement for you, and what the proper dosage guidelines are.

What is CLA?

Simply put, CLA is a fatty acid. It is most commonly found in beef and dairy products. You are probably wondering why you might want to put more fatty acid into your body. Unlike many other types of fat that clog your arteries and increase inflammation, this one is thought to provide a wide range of health benefits.

CLA is also classified as a trans fat, which again, is usually a bad thing. The reason CLA is still good for you is it can stop LPL (Liloprotein lipase) from doing its job. Since LPL’s job is to break down fat in a way that your body can store it, blocking it means your body ends up storing less fat. CLA tends to act more like an amino acid than a fat in your body, which is the main reason it is considered beneficial.

What are the Benefits of CLA?

There is a long list of reasons why people are incorporating CLA supplementation into their lives. Here are some of the most popular ones:

Muscle Gains

One of the biggest groups of people who use CLA supplements is bodybuilders. There have been numerous studies showing that it can increase muscle body mass. One important thing to note is that CLA is more effective for bodybuilders who are relatively new to the activity.

The main theory behind this is that experienced bodybuilders already have a great muscle to fat ratio. Another important thing to be aware of is that athletes in the studies that showed increased muscle mass were using relatively high doses of CLA.

Weight Loss

High levels of CLA can help you boost your basal metabolic rate, which is a fancy way of saying how much fat your body burns while at rest. Whenever your body is using its calories efficiently, fewer of them are turned into fat. Many studies have shown that CLA is particularly good at burning belly fat. This is good news for people at risk for cardiovascular disease. Some studies, as well as users, report that CLA supplementation helps you feel fuller, longer. This can lead to you consuming fewer calories in the first place.


CLA has been proven to be a potent anti-inflammatory agent. This is incredibly important to people with a wide variety of health concerns. People with heart disease, depression, arthritis, asthma, heartburn, and high cholesterol can all see an improvement in their condition with a reduction in inflammation. Lower inflammation is also a sign that the body has experienced less free radical damage, which is linked to a lower cancer risk.

Regulate Blood Sugar

It is strongly suspected that CLA plays a role in insulin regulation. As a result, it can help people with diabetes or who are pre-diabetic. More research is needed before there can officially be a link between the two.

Improve Immune Function

Animal studies have shown promising results for CLA enhancing the immune system as well as acting as an anticarcinogenic. CLA can help your immune system in a number of ways, from regulating your hormones to controlling your blood sugar levels.

Reduce the Risk of Heart Disease

Improving your levels of CLA can prevent several types of heart disease. It is thought to reduce the risk of your arteries hardening, also known as atherosclerosis. Additionally, it can prevent the deposition of lipids and plaques in arteries. This can help slow down or even prevent many forms of heart disease.

There are several other areas that CLA has shown promise in. They include bone growth, reducing food allergies and sensitivities, and an exciting reduction in the risk of cancer.

Side Effects of CLA Supplementation

When taken appropriately, there are few risks of CLA supplementation. Taking too much of it, however, has shown to have a few adverse effects. The most notable is a build-up of fat in the liver. This can lead you down a path toward metabolic syndrome and diabetes. A high dose would be more than 6,000 milligrams per day. Since 3,000 milligrams is an effective dose for most people, this should never be an issue.

Some of the less serious, and slightly more common side effects of CLA supplementation include stomach pain, diarrhea, nausea, and gas. Since CLA causes you to burn through fat more quickly, it may make you feel a bit tired as your body adjusts.

Enough research has not been done on the effects of CLA supplementation in pregnant and nursing women for it to be considered safe.

Dosage Guidelines for CLA Supplementation

Typically speaking, the recommended daily dose of CLA is between 3 to 5 grams per day. Many studies show the ideal dosage to be 3.2-3.8 grams daily. When shopping for supplements, you will likely see the amount of CLA given in milligrams instead of grams. Just remember – 1000 milligrams of CLA is 1 gram. You can take your capsules or soft gels however you want, but they should be taken with meals.

Some people find it better to take it 30 minutes prior to eating. Keep in mind, supplements of any kind can be hard on an empty stomach. If you are aiming for 3 grams, consider taking one 1000 mg capsule at (or half an hour before) breakfast, lunch, and dinner.

As with most health and fitness supplements, keep in mind that you will not see the benefits right away. Most commonly, it takes people 12 weeks to notice the impact of CLA supplementation. Since most CLA supplements are stimulant free, you can stack it with other supplements safely. This is commonly done with L-carnitine. Bodybuilders and people who are serious about weight loss are more likely to combine CLA with other supplements.

CLA in Your Diet

As previously mentioned, there is CLA in some of the things you are likely eating already. The exception to this would be for vegans and vegetarians. It’s found in beef, eggs, dairy, nuts, and even goat or sheep meat. Consuming these things is a way to raise your levels of CLA.

One interesting thing to note is that the amount of CLA is much higher in grass-fed animals than it is in grain-fed ones. Unfortunately, most of the animal products consumed in the West are from grain-fed animals. Eating enough grass-fed animal products to raise your CLA levels the way supplementation would be very expensive.

It is important to know that the CLA in supplements, which is derived from safflower oil, is slightly different from what you get from animal products. The CLA in supplements is not quite as effective, however, it is much easier and cheaper to get. You would have to eat about a pound of cheese, two pounds of beef, and drink close to 100 ounces of milk to see the weight loss benefits that 3-4 grams of CLA from a supplement can give you.

What to Look for in a CLA Supplement

You will want to make sure you are getting a high-quality product that is safe to take when shopping for your CLA supplement. There are several things to check out before making your final decision. They include:

Active CLA Quantity

You are looking for something that provides you with the correct amount of CLA to help you achieve your goal – most likely 3,000 to 4,000 milligrams. If the recommended daily dose is less than you want, it may have other ingredients that are unsafe in large quantities, so be sure to check the other ingredients before upping the dose.

Also, be aware that a product that has 1,000 milligrams of CLA may be “per serving”, requiring you to take 2 or 3 capsules to get to that number.

Ingredient Quality

Generally speaking, your body does not need any artificial ingredients such as colors or preservatives. Always seek the most natural product you can while still getting the job done.

CLA Freshness

Since CLA is a fatty acid, it can oxidize quickly in high temperatures if it has been put in a sub-par capsule. If this has occurred, the CLA can actually cause health problems instead of fixing them. Look for products that have been made in the USA in a GMP facility. Also be sure to check for the expiration date. If the product does not have one, consider that a red flag.

CLA Source Origin

All supplements on the market derive their CLA from safflower oil. Your job is to make sure that a product has a listed minimum CLA content (ideally 75% or higher.) Many people also prefer a non-GMO product. You want a pure CLA over a proprietary blend.

Stimulant Content

Although not extremely common, some CLA supplements have caffeine or other stimulants in order to give people an extra boost for the gym.

If you are at all sensitive to these items, double check that your CLA supplement does not have them. They can be especially harmful to people with anxiety. In most instances we’d recommend you opt for a CLA supplement without caffeine, you can always supplement that separately if required.


If you have an allergy, you are probably already in the habit of checking for its presence in anything you take. Be sure your supplement was not manufactured in a facility that also processes soy, nuts, milk, or gluten if you are sensitive to those things.

Vegan/Vegetarian Suitability

Many CLA supplements have bovine gelatin listed among the ingredients. If you are concerned about this, you can find vegan and vegetarian-friendly supplements. They’re a little harder to come across, but they’re out there if you look hard enough.

Final Thoughts

If you are in the market for a weight loss aid that does not have a lot of harsh stimulants or other negative side effects, CLA supplements may be a good choice. As long as you dose responsibly, the benefits outweigh the risks by far. Just be sure to pair your supplement with a good diet and exercise, and don’t expect miracles overnight.

The effectiveness of CLA for achieving it’s purpose is much less in doubt when compared to other supplements such as DHEA or even Glutamine supplements.

For those looking into CLA supplementation for other health benefits, be sure to consult your doctor before changing your current treatment. While CLA shows amazing promise, more research is required before the whole list of benefits can be considered conclusive.
